Mantracourt Electronics Limited T24-SO User Manual
Introduction / Overview
The T24-SO creates a serial output which can include data from up to 8 devices and optionally sum them. The
output is suitable for connecting to a printer, serial display or for feeding directly into a PC, PLC or any device
that is capable of using numeric values in readable ASCII format.
The actual serial output can be designed by the user using multiple lines which can include free text or tokens
which can represent real data. i.e. <V1> would be decoded as the value from input 1 when the print is
triggered.
Printing can be triggered from a contact, an external command or the arrival of a specific Data Provider
message.
The serial output can consist of a single line of data suitable for feeding into an LED display module or a more
complex multi-line result that can contain a mixture of fixed and variable data suitable for tickets, receipts etc
for printed output.
Communications Overview
The T24 range of telemetry devices each have a factory set unique ID.
Data is shared between devices using Data Provider messages. A device generates these messages which can
then be used by many other devices simultaneously.
These messages ( or packets ) of information contain a single value of data and each is identified by a Data
Tag.
The Data Tag should be unique for each message.
ID
Identifies each device
Each device has a unique ID that is factory set. This is represented as a 6 character hexadecimal
number consisting of the digits 0 to 9 and the letters A to F.
I.e. FFD3BE
Data Tag
Identifies each Data Provider message
A Data Tag consists of a 4 character hexadecimal number consisting of the digits 0 to 9 and the
letters A to F. The Data Tag can be changed by the user but the factory default is to match the
last 4 characters of the device ID.
I.e. An acquisition device of ID FFC12B would have a default Data Tag of C12B.
When a device consumes data (i.e. a handheld displaying data from an acquisition device) all it is doing is
listening to all of the Data Provider messages and selecting the one it wants to use. It then extracts the data
and displays it.
Some devices that use Data Provider messages also need to know the ID of the device providing the data. This
is necessary if that device needs to specifically wake the data providing device as opposed to using a broadcast
wake that will wake all devices on the same channel and using the same encryption key.
Pairing offers an automated method of hooking a provider and consumer of data together. However, some
devices may require you to manually enter Data Tag and ID information so it would be beneficial to the user to
understand the above mechanism.
Configuration Overview
Once it has been determined how many devices are feeding data to this device you need to record the Data Tag
that each of these devices are attaching to their Data Provider packets.
These Data Tags are then entered into the ValueDataTagx parameters. Once the rate at which this data arrives
is known you can enter the Timeoutx values.
Leave unused ValueDataTagx parameters with a value of zero to ensure that they are not checked for timeouts
and do not contribute to gross or net sums.
When a data provider packet arrives whose Data Tag matches one of those in the ValueDataTagx parameters
the value it contains will be placed in the Valuex parameter.
If data does not arrive from a device within the Timeoutx period then any reference to either the individual Vx
tokens or one of the summing tokens will result in ------ rather than a numeric value.

The actual serial output can now be constructed using Line1 to Line25. These parameters take text into which
you can insert tokens. When a 'Print' is generated these lines are parsed and tokens replaced with the values
they represent and the resulting data sent to the serial port.
A 'Print' is generated by either activating the switch input when SwitchMode is set to zero or by receiving a
Data Provider packet whose Data Tag matches the PrintDataTag parameter.
When a 'Print' is executed each of the parameters Line1 to Line 25 will be parsed. Every token will be evaluated
and replaced with the live value.
Getting Started
To attach acquisition devices to the T24-SO we must first ensure that the appropriate devices are transmitting
their values at a suitable rate such as the default of 3 per second. Then we can configure the module to use
the data from these devices.
Configuration must be done with the T24 Toolkit software and a base station.
Connecting Power
T24-SO
You will need to connect power and serial to the T24-SO for it to operate. Only power is required to enable
configuration using a base station and the appropriate toolkit software.

T24-SO Operation
The only way to affect operation of the T24-SO is as follows:
 The digital input (switch input) which may trigger an output/print or tare the summed value.
 Arrival of a data packet identified with a Data Tag that matches what the T24-SO uses to trigger an
output/print.
 Arrival of a command to trigger an output/print or to tare or zero etc.
Configuration
This section explains how to install software and connect the required devices together. Please note that you
will need the T24 Toolkit software and a T24-BS base station to allow your computer to communicate with T24
telemetry devices.
Installation
T24 Toolkit
To configure the devices we must use the T24 Toolkit software application. This can be downloaded from our
web site or may be shipped with your products.
Install this on a PC or laptop.
Run setup.exe and follow the prompts to install the software.
T24-BSu Base Station
If you have a USB version of the base station (T24-BSu) then you just need to plug this into a USB socket on your
PC. If you are using an alternative base station then please refer to the appropriate manual.

Analyser
The analyser page is provided as a tool and will not normally be needed unless you plan to change channels and
want to find the best channel to select, or to diagnose poor communications issues.
This page shows the radio signal levels detected across all the channels available to the T24 series of devices.
Using this tool may help in detecting noisy areas and allow you to decide on which channels you may want to
use.
The above charts show the traffic from a Wi-Fi network and it can be seen to be operating over channels 6 to 9
and it would be best (though not essential) to avoid using these channels.

Input Settings
Here you can set the action to take when the switch contacts are closed, set the Data Tag that will trigger an
output and also set the Data Tags of the data used as the inputs along with how the data is formatted.
Items you can change:
Waker Duration
Enter the number of seconds the display module will attempt to wake
acquisition modules when it is first powered up. Enter zero to disable this
feature. NOTE: all acquisition modules on the same radio channel as the
display module will be woken. Use the SleepDelay settings in the acquisition
modules to let them return to sleep after the display module is switched off.
This is only available for firmware versions 1.08 and above.
Output Trigger Data Tag
Enter the Data Tag which, on arrival, will trigger an output (I.e print). Note
that Min Interval setting on the Output Settings page may stop this from
working at the rate at which the data arrives.
This is usually set to the Data Tag of one of the inputs.
Example: If the output was being sent to a serial display the same Data Tag
would be assigned to input 1 and the output trigger so that each time data
arrived the output would be sent to the serial display.
Switch Mode
Click to select either:
Print – Triggers an output from the serial port. Note that Min Interval setting
on the Output Settings page may stop this from working at the rate the
contact closes.
Gross/Zero – Toggles the measurement mode between gross and net. When
switching to net the net value is zeroed (tared). This will affect the value of
the <N> token which is the net value of all summed inputs.
Remote data Tags and Timeouts

Mantracourt Electronics Limited T24-SO User Manual
Timeout
Format
NOTE: You can click the P button to retrieve the Data Tag of a device by
pairing to it which is usually initiated by power cycling the module.
Clicking the X button zeroes the entered Data Tag.
Enter the timeout in milliseconds for this input. If a new Data Provider packet
does not arrive within this time and reference to this input value (via token
<V1> for example) will result in an output of -------. This also applies to a gross
or net reading derived from this input.
Describe the format that this value is to take when output. You specify integer
digits and decimal places by entering a format consisting of zeroes and
decimal points. i.e. 00.000
NOTE: The integer value of data takes precedent over your defined format so
if you defined a format of 0.0 and data of value 100.8765 arrived it would be
represented as 100.8

Output Settings
Here you can change various settings that influence the output from the module.
Items you can change:
Duplicate
Whether to produce the same output twice each time an output is triggered.
Useful, for example, with a printed output where a customer requires a
receipt.
Min Interval
Minimum time allowed between triggered outputs entered in milliseconds.
Triggers arriving within this time since the previous trigger will be ignored.
Example: A Data Tag is used to supply data to input 1 and is used to trigger an
output. This data arrives at a rate of 50 per second but the output is
connected to a serial display which would have problems if it were sent data
at this rate. By setting the Min Interval to 300 the outputs would be limited to
3 per second even though the data was arriving at a higher rate.
Gross Text
Enter text to replace the <GN> token with when the device is in gross mode.
Net Text
Enter text to replace the <GN> token with when the device is in net mode.
Print On Error
Whether to trigger an output when any input device fails to deliver new data
within the timeout period.
Example: Data arrives which is used as input 1. This same data tag is used to
trigger an output which is sent to a serial display. Normally if the data fails to
arrive the display would not get updated as no output would occur. By setting
this property an output would be triggered when the data failed to arrive thus
setting the serial display which would show ------- instead of the value when
<V1> is decoded.
Log Number
Enter a log number that is used when the <LOG> token is decoded. Each time
13
Mantracourt Electronics Limited T24-SO User Manual
an output is triggered this log number is incremented. This number will wrap
to zero once it reaches the maximum value displayable due to the Log Digits.
Log Number (Non Volatile)
The Log number defaults to being volatile. Power cycling the T24-SO will
revert the log number to the value seen on this page. This is ideal for when
you have a fast output and you want the outputs to be numbered sequentially.
i.e. with a fast output being sent to a data logger.
Sometime it is required that the log number is Non Volatile, that is, the log
number is restored each time the T24-SO is power cycled.
This is useful when the output is used to drive a printer, for example, and the
log number acts as a unique number on the customer ticket.
When set to Yes the module must store the new Log Number each time it is
incremented. This takes time and also uses up the finite write cycles of the
internal flash memory. Therefore it is recommended that turning on the Non
Volatile option is only done when the output (containing a <LOG> token) is
triggered at 30 second intervals or less.
Log Digits
Set the number of digits to display when the <LOG> token is decoded.
Example: If this is set to 2 then the log number will count up to 99 before
resetting.
Line Delay Char
As the serial output is has no hardware handshaking it is sometimes necessary
to limit the rate at which the output is sent. This is most apparent with
multiline outputs to a printer.
Example: A printer requires a 0x0A (decimal 10) character (linefeed) to be
sent at the end of each line to cause the printer to actually print the line.
This character would be embedded in the actual designed output and the Line
Delay Char set to 0A so each time a line is sent to the printer a delay occurs
before the next part of the output is initiated. The delay is set by Line Delay.
Line Delay
The delay in milliseconds that occurs when the Line Delay Character has been
sent to the output.
Mantracourt Electronics Limited T24-SO User Manual
14
Output Scaling
This page allows effective conversion between units. i.e. Although all devices supplying data are configured in
Kg you can get a printed output in Lbs.
Items you can change:
Custom Display Scaling
This can be used to change the displayed value to a different unit or to
otherwise scale it. You simply enter the original and required values at a low
and high point.
Example: If a T24-SA was supplying data in Kgs and you wanted to show tonnes.
You would keep both the low points at zero. Enter At High Input Value of 1000
and Display Should Read Value of 1.
NOTE: This affects all inputs and sums (both gross and net). All tokens will
effectively be decoded using the new scale factor.
15
Mantracourt Electronics Limited T24-SO User Manual
Output Design
This is where you define the actual output based on free text and tokens.
Tokens are special codes contained within angled brackets <token> which have special meanings and are
converted to actual values once an output is triggered.
See list of tokens at the bottom of this section.
Items you can change:
End Of Line Token
Design Area
When you press the Enter key on the keyboard we need to know which token
to include in the design area. For single line outputs this is not an issue but for
multiline printer outputs for example it becomes important. You need to know
what character is used to cause the printer buffer to be printed. For this you
will need to refer to the printer manual. Some printers just require a Carriage
Return <0D> and some may require a Line Feed <0A> or some may require both
<NL>. You would need to set the Line Delay Char on the Output Settings page
to the appropriate character. And here you can select whether to use that
character each time Enter is pressed or you can opt for <NL>.
This is where you create your output using a mixture of free text and tokens.
See the example in the screenshot above.
To enter a token you can type it in or double click the token list on the right
of the page (a single click will display the description of the token).

Here you can set a system zero.
Items you can change:

Clicking this will store the current values on all inputs and subtract the value
from all subsequent outputs thus rendering the current input as zero.
Example: A 4 input weigh platform will have calibrated acquisition modules
but when the actual platform structure is in place each module has a weight
value thus the gross value is 50Kg.
By performing a system zero (with all inputs operational) this is zeroed away
so next time the T24-SO is powered on the same input will yield a zero result.
Clicking this will remove all system zeros and restore all outputs normal.

Zero Settings Advanced
This advanced section allows the use of a specially configured external module to supply the system zero value
for the handheld to use.
Example:
The same T24-SO is used with a truck that picks up different trailers and is required to display the sum of 4
strain gauges connected to each trailer (Using T24-SAs).
Because each trailer will have a different system zero requirement we would add a further device to each
trailer set to transmit the system zero value. It is the Data Tag that is entered here.
Note: On all trailers the acquisition module sets share the same Data Tags.
Items you can change:
Data Tag Enter the Data Tag of the message to use for the external system zero.
ID
Contains the ID of the device used to supply the external system zero. This is only necessary to
provide a visible record of the remote device and is shown to keep compatibility with the Mode

You do not need to enter anything here although it will be filled in automatically if you perform a
pair to retrieve data.
P
Click this to give 5 seconds to perform pairing to automatically provide the Data Tag and ID from a

Installation
Overview
Radio performance at microwave wavelengths is very dependent upon the operating environment; any
structure within the operating region of the radios will give rise to three effects:
Obscuration. Obscuration will result in reduced range and occurs when an obstruction masks the line-of-sight
between radios.
Aberrations to the horizontal and vertical space patterns. Distortion of these patterns may occur if
structures or objects are placed in the near or intermediate field of the antenna. The effect will be to distort
the coverage patterns, adversely affecting range and link quality.
Reflection. Any object placed in line-of-sight of the transmit antenna will result in signals arriving at the
receiver by an indirect path. Degradation of performance due to reflection (multipath effects) appears as
reduced range or poor link quality.
Any of the above will cause poor RSSI figures, an increase in the packet loss rate and in extreme cases
complete loss of signal. Fortunately, if consideration is given to these effects at the integration stage then a
good quality link will be obtained.
Guidelines for product design:
When selecting materials for product enclosures, preference should be given to fibreglass, light coloured ABS or
Polypropylene; at the wavelength of 2.4GHz radio other materials will adversely affect the signal by
attenuation, refraction or change in polarisation.
If the application demands that the radio is fitted inside a metal enclosure then ensure that the specified
clearances are maintained around the antenna and design in a fibreglass RF window at least as large as the
clearance dimensions but ideally as large as possible.
RAD24i radios fitted inside a product should be oriented so that the chip antenna will be vertical when the
product is in its normal operating position.
Guidelines for installation:
When planning installations ensure that line-of –sight between nodes is maintained and that objects or
structures are kept at least one metre away from antennae wherever possible.
To avoid poor link quality between a RAD24i radio and a handheld device ensure that the RAD24i is mounted so
that the chip antenna is vertical. Improvement may also be obtained by altering the height above ground of the
RAD24i; a small increase or reduction in antenna elevation will often improve reception.
Range underwater is only a decimetre or so depending on packet rate. Best performance underwater is
obtained by using low packet rates and immersing water-proofed antennae rather than water-tight enclosures
containing the antennae.
